But when you yank a weed by hand, it often breaks off, leaving the root behind. That means it will quickly re-sprout.
Using Roundup Gel in just one hand, and at the click of a button, you can release the precise amount of gel needed to target the weeds without risk to other nearby plants. So, for crowded borders where you want to protect your beautiful plants, this product is the perfect choice.
Keeping weeds under control isn’t always a question of digging or spraying. A physical barrier (called a mulch) will also help to prevent weed seeds from germinating. This light-excluding layer on the soil surface can be of gravel, bark chippings or easily obtained organic matter.
2. Use a gel weedkiller such as Roundup Gel
In order to get the best performance from any weedkiller, we would always advise to apply the product when the weather is fair and not to apply in windy conditions. Do not apply if rain is expected within 6 hours of application as this could reduce the efficacy of the product.
The gel formulation sticks to the weed leaf and stays there, so there’s no dripping or running off onto the soil or surrounding plants. Simply click the button and apply all the gel that appears across the weeds leaves, then in the following days you will start to see the weed die off – Simple!
1. Mulch your flower bed
